CAP FOR CONTAINERS.

Application filed April 7, 1923. Serial No. 630,468.

To ail whom if may concern: I

Be it known that I, OSCAR B. W'nnnnn, a citizen of the U nited States, and a resident of Middletown, in the county of Middlesex' and State of Connecticut, have invented new and Improved Caps for Containers,

of which the following is a specification.

My invention relates to that class of devices that'are commonly used, in connection with various types of containers, the contents of which have to be replenished at more or less frequent intervals, and an object of my invention, among others, is

to provide a cover for these containers that shall have a maximum efiiciency both as to tightness to prevent the contents of said containers or similar devices from splashing or leaking out through said cover, and as to means whereby the'mouth of a container may be opened .or closed and the cover may also be locked by a very simple and easy operation of a handle, A further object of the invention. is to provide a cover that can be easily attached to the opening of a container in common use with-.

' out the aid of tools to replace the ordinary 'removable cover supplied therewith, and

so constructed that it will not necessitate its removal from the container when it IS desired to uncover said opening.

One form of device embodying my in vention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated inthe accompanying drawings, in which- Figure. 1 is a view in vertical section through a cover embodying my invention, the operating handle, being shown in full.

Figure 2 is a similar view of the device taken at right angles to the point of view of Figure 1.

Figure 3 is a plan view of the device showing the cover in the unlocked position.

It is a Well known fact, especially in connection with covers which are removably attached to containers'such as are used for automobile gasoline tanks, radiators and the like, that require the frequent removal of the cover for the purpose of filling the container, that it is-often forgotten to replace the cover, which fact being unnoticed part of at the time results in said cover being consequently lost. \Vith my device as hereinafter described this cannot happen.

in the accompanying drawings the numeral 7 denotes a. ring shaped supporting member having a screw threaded portion 8 which provides a suitable means by which my device can be secured to the threaded flange 9, that is commonly used in conncction with containers of the character herein disclosed. The numeral 10 denotes a section of one of these containers.

The supporting member '7 has vformed thereon cars 11 to which is hinged, by a pin 12, anear 13 secured to a cover/plate 14. This cover plate has a flange 15 which overhangs the edge of the supporting memher 7 and also serves to contain within the cover plate a washer 16. An operating handle 17 has an operating stud 18 projecting throu h the cover plate and on which a bafile p ate 19 is mounted. The end of thisstud' is squared as at 20 and has'secured thereto a locking bar 21 supplemented by a washer 22.

The locking bar 21' engages locking flanges 23 on the sup orting member 7, which flanges are preferably an integral said member. These locking flanges have an inclined cam shaped surface at their under sides and they are separated by spaces 2 124 which permit the passing. of the locking bar 21'to its proper position when the cover is closed.

- It'can readily be seen that when the cover is closed the ends of the locking bar pass through the spaces 24-44: and that by a simple turn of the operating handle 17 this bar is turned into contact with the cam surfaces of the locking flanges that tend to pull down the cover tightly into engagement with the sup ortin: member 7. The recess in the ear 13 being largerthan the pin 12 it will allow the cover late suflicient play to enable it to proper yseat. Studs 25 on the locking flanges are employed as stops to limit the travel of the locking bar.

As the. locking bar21, as shown herein, is formed of sprm material it will tend to keep thecover tig tly closed and still will not bind nor become loose. In connection with covers for containers of the character By the use of the baflieplate any leakage due to the splashing of the contents is prevented, since this plate will obstruct the the locking members.

passage of the contents through the opening 27 and part of the contents which may happen to splash through the opening 26 will flow back into the container. This bafiie plate is T so constructed that. it also serves as a spacer plate to properly position It will be seen that my improved device may be attached to the outlet of a container in the same manner as the, ordinary screw cap therefor, and after such attachment will provide a cover that cannot be misplaced.

I claim:

1. A container-cap including a supporting member, a closure member hinged to one end of the supporting member, a locking bar rotatably supported within the cover with the opposite endsthereof cooperating with the supporting member for retaining the closure member in closed position and a bafile plate interposed between the closure member and locking bar for retaining the locking bar properly positioned relative to the supporting member.

2. A container .cap including a supporting member, a closure member hinged to one end of the supporting member, a locking bar rotatably supported within the cover with the opposite ends thereof cooperating with the supporting member for retaining the closure member in closed position, a balfie plate interposed between the closure member and locking bar for retaining the locking bar properly positioned relative to the supporting member, the supporting means for the lockingbar including'a stud rotatably mounted in the closure member with the locking bar supported at the lower end of the stud, and an interlocking connection between the stud and locking bar.

3. A container cap including a supporting member, a closure member hinged to one end of the supporting member, a locking bar rotatably supported Within the cover with the opposite ends thereof .cooperating with the supporting member for retaining the 010- sure member in closed position, the supporting bar for retaining the latter properly positioned -on the stud.

4, A container cap including a supporting member, a closure member hinged to one end of the supporting member, a locking bar rotatably supported within the cover with the opposite ends thereof cooperating with the supporting member for retaining the closure member in closed position, the supporting means for the locking bar including a stud rotatably mounted in the' closure member with the locking bar supported at the lower end of the stud, an interlocking connection between the stud and locking bar, including the provision of a polygonal portion on the stud, a similarly shaped opening in the locking bar. receiving the polygonal portion and a. baffle plate of dished disk formation supported on the stud and engaging the closure member and lock ing bar for retaining the latter properly positioned on the stud, and the adjacent upper portion of the stud being cylindrical in cross-section and supporting the bafiie plate.
